Company Background

CirrusWorks is the leader in dynamic bandwidth management. The CirrusWorks Governor optimizes traffic during peak congestion periods to ensure fast and reliable Internet performance for all users. Only CirrusWorks employs AutoAlgorithms™ that adapt to unpredictable traffic patterns in real time, without the need to pre-configure static rule sets or policies. CirrusWorks enables organizations to reduce network congestion and provide fast, reliable internet while maximizing their existing infrastructure.

At CirrusWorks, our mission is to improve Internet performance in a simple, efficient and effective way. CirrusWorks was founded by veterans of the technology services industry who saw first-hand the need for better, smarter, faster tools to manage IP network performance. Collectively, they have built businesses that enable digital communications at home, on the road and at the workplace, both domestically and world-wide. They have personally contributed to multiple chapters in the recent history of telecommunications technologies: from the growth of global financial transaction networks, to the expansion of public WiFi networks in hotels. They have witnessed the onset of mobile communications, video streaming and cloud-based systems, all of which require more data, more infrastructure and more and more resources to manage the exponential growth of bandwidth congestion. It was from their experience providing networking solutions in this data congestion environment that the idea of CirrusWorks was born.

Serving a broad customer base including leading education, hospitality and the public sector, CirrusWorks is changing the way organizations manage network performance. CirrusWorks is headquartered in Tysons Corner, VA.
